This is a pre-req to bring the Node system under object protocol.
Most of the code reflects the current code in the Node system.

  • Use new instead of init so subclass can define their own constructors
  • Allow register via name, besides type index
  • Introduce necessary runtime C API functions
  • Refactored Tensor and Datatype to directly use constructor.

will you shadow the python object by using filename object.py?

I think we will not, given that object is not a keyword, as long as you do not do from tvm._ffi import object



class Object(_ObjectBase):
"""The VM Object used in Relay virtual machine."""
